Definitions

  • the present disclosure relates to an air intake and blowout tool allowing intake or blowout operation by introducing compressed air into the tool in the shape of a cylinder and thereby generating a high volume of air flow inside the tool along the central axis of the cylinder.
  • the air intake and blowout tool has a cylinder body including along the central axis of the cylinder an air passage allowing air to flow through.
  • the cylinder body has openings on one end thereof that constitutes an air intake port and on an opposite end thereof that constitutes an air blowout port.
  • a compressed air introduction part for introducing into the air passage compressed air pressurized by a compressor is provided in a midsection of the cylinder body.
  • the compressed air introduction part has a shape extending annularly around the central axis of the cylinder.
  • the compressed air introduction part introduces compressed air into the air passage toward an air blowout port side of the air passage to generate negative pressure in the air passage on an air intake port side thereof and thereby produce an air flow in the air passage. Air is thus sucked in the air passage from the air intake port and blown out from the air blowout port. Therefore, it is possible to perform operations on one hand for scattering away swarf and water drops by utilizing the air blowout port side of the air intake and blowout tool and on the other hand for sucking and collecting dust and waste by utilizing the air intake port side of the air intake and blowout tool.
  • Patent Literature 1 International Publication WO2016/088154
  • US 7 354 029 B1 discloses an air intake and blowout tool with a cylinder body having an air intake port and an air blowout port according to the preample of claim 1.
  • GB 1 431 810 A relates to another air intake and blowout tool of the state of the art.
  • the compressed air introduction part has been generally seen to be favorable to have a shape decreasing in diameter and gradually closer to the central axis of the cylinder toward the air blowout port side to open into an inner circumferential surface of the cylinder body.
  • the inventor has found, as a result of diligent study, that when the compressed air introduction part has the shape as described above, the cylinder body inner circumferential surface forming the compressed air exit port on the air intake port side has a pointy shape to be progressively thinner toward the air blowout port side, so that small volume of the compressed air introduced from the compressed air exit port into the air passage flows so as to turn around along a portion of the pointy shape and thus advances toward the air intake port side of the air passage, causing the energy loss at the portion of the pointy shape.
  • an object of the present disclosure is to provide an air intake and blowout tool able to increase intake and blowout volume.
  • the present disclosure is characterized by introducing compressed air into an air passage by applying the Coanda effect.
  • an air intake and blowout tool including a cylinder body that includes along a cylinder-central axis an air passage having an air intake port on one end and an air blowout port on another end; and, in a midsection of the cylinder body, a compressed air introduction part capable of introducing compressed air into the air passage; the compressed air introduction part configured to introduce compressed air into the air passage toward an air blowout port side of the air passage to generate negative pressure in the air passage on an air intake port side thereof and thereby produce an air flow in the air passage, and thus providing air being sucked from the air intake port into the air passage and blown out from the air blowout port.
  • the following solutions are then applied.
  • the compressed air introduction part includes a compressed air exit port formed in a shape of a ring that extends circumferentially about the cylinder-central axis and slot-shaped extending straight along a radial direction of the cylinder body to open into the air passage.
  • An air passage forming inner circumferential surface of the cylinder body on an air blowout port side of the compressed air exit port includes an annular protuberance surface portion protruding toward a radially inner side of the cylinder body greater than an air passage forming inner circumferential surface on an air intake port side of the compressed air exit port and extending circumferentially about the cylinder central axis.
  • the annular protuberance surface portion includes a protuberance surface shaped to extend from a peripheral edge portion of the air blowout port side of the compressed air exit port toward the radially inner side of the cylinder body and to then gradually curve and extend toward the air blowout port side.
  • the air passage forming inner circumferential surface of the cylinder body on the air intake port side of the compressed air exit port includes an annular stepped surface portion extending along a peripheral edge portion of the air intake port side of the compressed air exit port.
  • the cylinder body includes first and second cylinder members each open at both ends.
  • the cylinder body is configured to be assembled by inserting one end side of the first cylinder member into an interior of the second cylinder member to screw one end side of the second cylinder member with an outer circumferential surface of a midsection of the first cylinder member.
  • the compressed air introduction part is configured to be formed of a portion surrounded by an outer circumferential surface of the one end side of the first cylinder member and an inner circumferential surface of a midsection of the second cylinder member.
  • the inner circumferential surface of the midsection of the second cylinder member includes an annular face extending along a direction orthogonal to the cylinder-central axis and opposing one end face of the first cylinder member.
  • the compressed air exit port is configured to be formed between the one end face of the first cylinder member and the annular face.
  • the compressed air introduced in the compressed air introduction part is then introduced from the compressed air exit port to the air passage in an interior of the cylinder body to advance linearly toward the radially inner side of the cylinder body. While the annular protuberance surface portion is provided on the air blowout port side of the compressed air exit port, no wall is provided on the air intake port side of the compressed air exit port.
  • the compressed air introduced from the compressed air exit port into the air passage flows smoothly along the protuberance surface of the annular protuberance surface portion toward the air blowout port side due to the Coanda effect. In this manner, the compressed air is introduced into the air passage to be directed toward the air blowout port side of the air passage, thus resulting in producing the air flow in the air passage.
  • the compressed air exit port is slot-shaped extending toward the radial direction of the cylinder body and thus the cross-sectional shape of the cylinder body inner circumferential surface forming the compressed air exit port on the air intake port side is not acute angled.
  • the phenomenon that a part of the compressed air introduced from the compressed air exit port into the air passage advances toward the air intake port is less likely to occur. This enables reduced energy loss around the compressed air exit port and increased volume flow rate of the air in the air passage.
  • the compressed air exit port does not need to be wider and thus the flow rate of the compressed air introduced from the compressed air introduction part into the air passage is not reduced.
  • the cylinder body inner circumferential surface on the air intake port side of the compressed air exit port is positioned radially outwards from the cylinder body inner circumferential surface on the air blowout port side.
  • the air intake port is thus designed to have a larger diameter, enabling increased air intake volume in the air intake port.
  • circumferential walls of the first and second cylinder members are placed over one another at a midsection of the assembled air intake and blowout tool, resulting in the air intake and blowout tool having high rigidity.
  • the air intake and blowout tool then consists only of two components, allowing shorter assembly time to reduce assembly cost.
  • a gap formed between the first and second cylinder members serves as the compressed air exit port of the compressed air introduction part.
  • the first and second cylinder members thus do not require preceding machining processes to form holes or grooves for a compressed air exit port, enabling lower machining cost.
  • FIG. 1 illustrates an air intake and blowout tool 1 according to embodiments of the present disclosure.
  • the air intake and blowout tool 1 converts compressed air generated by a compressor (not shown) to a high-volume air flow, and is utilized for operations to scatter away swarf and water drops sticking on equipment by blowing the air and to suck in and collect dust and waste produced in a plant by using the air.
  • the air intake and blowout tool 1 includes a cylinder body 2 having, along a cylinder central axis C1, an air passage 2a that allows air to flow inside.
  • the air passage 2a has an opening on one end that forms an air intake port 2b and an opening on another end that forms an air blowout port 2c.

  • the annular rib portion 3c protrudes radially outwardly and extends circumferentially about the cylinder central axis C1.
  • An annular protuberance surface portion 30 is formed on an inner circumferential surface of the first cylinder member 3 on the one end side thereof.
  • the annular protuberance surface portion 30 projects toward a radially inner side of the cylinder body 2 and extends circumferentially about the cylinder central axis C1.
  • the annular protuberance surface portion 30 includes a protuberance surface 30a formed to extend from one end face of the first cylinder member 3 (a peripheral edge portion of a compressed air exit port 5a on an air blowout port 2c side, as described below) toward the radially inner side of the cylinder body 2 and to then gradually curve and extend toward another end side of the first cylinder member 3.
  • a blowout port side air guiding surface 3d continuous with the protuberance surface 30a is formed on a portion extending from a midsection of the inner circumferential surface of the first cylinder member 3 to the other end thereof.
  • the blowout port side air guiding surface 3d is tapered to increase gradually in diameter in a direction away from the protuberance surface 30a.
  • a tapered surface 4a is formed on an outer circumferential surface of the second cylinder member 4 on one end side thereof.
  • the tapered surface 4a gradually decreases in diameter toward the one end.

  • the second recessed groove 40 is shaped to have a wider groove width and to be shallow.
  • the second recessed groove 40 includes a belt-shaped bottom surface 40a extending circumferentially in an annular manner about the cylinder central axis C1, a first annular face 40b extending from one edge of the belt-shaped bottom surface 40a in a direction orthogonal to the cylinder-central axis C1, and a second annular face 40c extending from another edge of the belt-shaped bottom surface 40a in the direction orthogonal to the cylinder-central axis C1.
  • a compressed air introduction hole 40d opening in the belt-shaped bottom surface 40a of the second recessed groove 40 is formed penetrating at the midsection of the second cylinder member 4.
  • the compressed air introduction hole 40d is coupled to an L-shaped pipe 6 (see FIG. 1 ).

  • An annular fitting portion 4d corresponding to the annular rib portion 3c is formed in a portion continuous with the female thread portion 4c on the inner circumferential surface of the second cylinder member 4 on the one end side thereof.
  • a tapered air intake surface 4e and an intake port side air guiding surface 4f formed continuously with the air intake surface 4e are provided on the inner circumferential surface of the second cylinder member 4 on the other end side thereof.
